Page 21: User Exec Mode
Chapter 1 Using the Command-Line Interface CLI Command Modes Privileged EXEC Mode Because many of the privileged commands configure operating parameters, privileged access should be password-protected to prevent unauthorized use. The privileged command set includes those commands contained in user EXEC mode, as well as the configure privileged EXEC command through which you access the remaining command modes.
Page 22: Privileged Exec Mode
Chapter 1 Using the Command-Line Interface CLI Command Modes Interface Configuration Mode Interface configuration commands modify the operation of the interface. Interface configuration commands always follow a global configuration command, which defines the interface type. Use the interface interface-id command to access interface configuration mode. The new prompt means interface configuration mode.
Page 23: Line Configuration Mode
Chapter 1 Using the Command-Line Interface CLI Command Modes The supported commands can vary depending on the version of software in use. To display a comprehensive list of commands, enter a question mark (?) at the prompt. Switch(config-line)# ? To exit line configuration mode and to return to global configuration mode, use the exit command. To exit line configuration mode and to return to privileged EXEC mode, enter the end command, or press Ctrl-Z.

Chapter 2 Catalyst 2350 Switch Cisco IOS Commands mls qos srr-queue input dscp-map mls qos srr-queue input dscp-map Use the mls qos srr-queue input dscp-map global configuration command to map Differentiated Services Code Point (DSCP) values to an ingress queue or to map DSCP values to a queue and to a threshold ID.
Page 188 Chapter 2 Catalyst 2350 Switch Cisco IOS Commands mls qos srr-queue input dscp-map You can map each DSCP value to a different queue and threshold combination, allowing the frame to follow different behavior. You can map up to eight DSCP values per command.

Because the weight ratios for queues 2, 3, and 4 are set to 0, these queues operate in shared mode. The bandwidth weight for queue 1 is 1/8, which is 12.5 percent.
Page 468: Srr-Queue Bandwidth Share
Chapter 2 Catalyst 2350 Cisco IOS Commands srr-queue bandwidth share srr-queue bandwidth share Use the srr-queue bandwidth share interface configuration command to assign the shared weights and to enable bandwidth sharing on the four egress queues mapped to a port. The ratio of the weights is the ratio of frequency in which the shaped round robin (SRR) scheduler dequeues packets from each queue.
Page 469 Chapter 2 Catalyst 2350 Cisco IOS Commands srr-queue bandwidth share Examples This example shows how to configure the weight ratio of the SRR scheduler running on an egress port. Four queues are used. The bandwidth ratio allocated for each queue in shared mode is 1/(1+2+3+4), 2/(1+2+3+4), 3/(1+2+3+4), and 4/(1+2+3+4), which is 10 percent, 20 percent, 30 percent, and 40 percent for queues 1, 2, 3, and 4.

Page 475 Chapter 2 Catalyst 2350 Cisco IOS Commands switchport mode To autonegotiate trunking, the interfaces must be in the same VLAN Trunking Protocol (VTP) domain. Trunk negotiation is managed by the Dynamic Trunking Protocol (DTP), which is a point-to-point protocol. However, some internetworking devices might forward DTP frames improperly, which could cause misconfigurations.

This command was introduced. Usage Guidelines For Layer 2 traceroute to function properly, Cisco Discovery Protocol (CDP) must be enabled on all the switches in the network. Do not disable CDP. When the switch detects a device in the Layer 2 path that does not support Layer 2 traceroute, the switch continues to send Layer 2 trace queries and lets them time out.
